Abstract
A system air fans integrated control apparatus for a computer system which has a plurality of heat sources and a plurality of air fans corresponding to the heat sources includes a plurality of detection units to detect the heat sources and output a plurality of temperature alteration parameter signals, a signal integration and determination circuit to receive and interpret the temperature alteration parameter signals to determine a rotation speed regulation signal, and an air fan driving circuit which is linked to the signal integration and determination circuit and an external driving power source. Upon receiving the rotation speed regulation signal the driving power of the external driving power source to the air fans is regulated synchronously. Thereby multiple heat sources are detected at the same time and multiple air fans are integrated to perform heat dissipating to reduce accumulating heat in the system environment.
